Pacifica is the epic tale of a great and vast Athenian Empire that ascends to power through the conquest of South America and forms a military alliance with China, known as the Pacifican Alliance. This new oceanic agreement directly threatens world security and American interests abroad. The North Alliance (an American and Russian military pact) quickly responses with aerial blockades and economic sanctions against the Pacifican member nations, which ultimately leads to World War IV. Western America and Siberia are invaded and come under occupation by the Pacifican imperial armies. The cities of Washington and Moscow are destroyed by surgical air strikes. A few years later, an Athenian Civil War breaks out on the home front, while the Pacifican forces continue to fight against the North Alliance. In Olympia (the capital city of Athenia) dividing factions of Loyalists (the Imperial Guard and the Alpha Corps) and Nationalists (Rebel Forces) battle each other for control of the empire, while the bulk of their military forces remain at the frontlines.The global conflict between warring superpowers progresses until eventually the Athenian Empire and its other supporting allies (The Fourth Reich, United Islam, and Aztlan) are defeated due to internal conflicts of rebellion and by the coalition of nations that had banded together; such as the Israeli Empire, United Europe, South African Union, Canada, New Hindustan, and Greater Persia. The neutral nations of the world finally enter into this global conflict of human struggle.
